Accepted Answer

VPC Service Controls define access to resources from outside a VPC using a perimeter. This feature is specifically designed for controlling access. VPC Firewall Rules and Cloud Armor Security Policies focus on network traffic and DDoS protection, whereas Private Google Access is about accessing Google services without an external IP.
